DETAILED DESCRIPTION

For the purposes of promoting an understanding of the principles of thedisclosure, reference will now be made to the embodiments illustrated inthe drawings, which are described below. The embodiments disclosed beloware not intended to be exhaustive or limit the disclosure to the preciseform disclosed in the following detailed description.

FIG. 1b is a perspective view of an embodiment of a portable medicalmonitor 20 (also referred to as “monitor 20”) in a first orientation.FIGS. 2a-c are top, front, and bottom views of monitor 20. As shown,monitor 20 comprises a housing 22, a display module 24 supported byhousing 22, a handle 26, a power button 28, an output interface 30, andconnector ports 32, 34, and 36. Monitor 20 has front and back sides.Display module 24 includes a display screen that defines the front sideand electronic circuits operable to receive, and then output to thedisplay screen, video data. The display screen may be a touch sensitivescreen that also functions as a user input sensor, in which case theelectronic circuits also include circuits to sense the position of theuser's fingers or input device, e.g. touch screen pencil, and to outputsignals including indicia indicative of the location touched on thedisplay screen.

As shown in FIG. 2c , housing 22 includes a front housing component 57removably attached to a back housing component 54. A securement cover 56is removably attached to back housing component 54. Securement cover 56can be removed to expose and provide access to a number of fastenersprovided to removably attach front housing component 57 to back housingcomponent 54. Example fasteners include screws and snap-fits.

FIGS. 3a and 3b are a back perspective and a side view of monitor 20.Monitor 20 comprises support features including at least handle 26 and alatching structure 82, described with reference to FIGS. 5a-5c ,including a pair of bracket latch receivers. Handle 26, described withreference to FIGS. 3a-4c , can be used to carry monitor 20 and canfunction as a table stand. Latching structure 82 is configured tosupport monitor 20 from a monitor bracket which can be clamped to an IVstand. Advantageously, the support features are positioned in a middlesection of the monitor to facilitate operation of the monitor in thefirst and second orientations. Rotating the monitor to place theconnector ports on the right or left side may be desirable in enclosedsettings, for example, which may provide limited accessibility to one orthe other side. Advantageously, connector rings are provided on one sideof the monitor that distinguish the right and left sides and allow auser to quickly determine which orientation the monitor is in.

Handle 26 comprises handle axles 51, 52 pivotally securing arms 46, 48to housing 22. Each handle axle is connected to the first end of one ofthe arms. Each handle axle traverses, at least partially, one of thegrooves 42, 44 to define a first section of the groove on one side ofthe handle axle and a second section of the groove on an opposite sideof the handle axle. The handle is pivotable about the handle axles to aplurality of positions including a first position, in which the arms arereceived by the first sections of the grooves, a second position, inwhich the arms are received by the second sections of the grooves, andintermediate positions between the first position and the secondposition. Monitor 20 further includes handle position brakes (describedwith reference to FIGS. 18 and 19), including the handle axles, to holdthe handle in one of the positions. Housing 22 includes a body 54 and acover 56. Cover 56 can be removed from body 54 to provide access tofasteners which can be removed to separate body 54 from display module24 and provide access to various internal components.

The back side, 65, of the housing includes grooves 42, 44 sized andshaped to receive, respectively, arms 46, 48 of handle 26. The back sideof the housing also includes a middle section 50 (shown in FIG. 4b )extending between the third side and the fourth side equidistantlybetween the first side and the second side, the middle section having aheight “H” less than 4.0 centimeters, preferrably less than 3.0centimeters. A central plane C_(P) passes through middle section 50.Each of the arms has a first end pivotally attached via a handle axle51, 52 to the middle section of the housing, as described further below,and a second end opposite the first end and connected to the bar. Handleaxles 51, 52 are shown on central plane C_(P). Grooves 42, 44 each havea portion 42 a, 44 a on one side of a handle axle and another portion 42b, 44 b on the other side of the handle axle. The portions of grooves42, 44 are sized and shaped to receive the arms of the handle. In FIGS.3a and 3b the arms of the handle are not drawn to scale.

Housing 22 also includes a video output housing recess 400 (describedwith reference to FIGS. 20a-c ) and a power receptacle assembly 500(described with reference to FIGS. 14a and 21). Additionally, housing 22includes an external heat sink 70.

Housing 22 has a first side 61 and a second side 62 opposite the firstside, a third side 63 and a fourth side 64 opposite the third side andorthogonal to the first side, a front side, and a back side opposite thefront side. Advantageously, monitor 20 can be rotated 180 degrees from afirst orientation to a second orientation. The first orientation may bereferred to as the “default” orientation and the second orientation maybe referred to as the “inverted” orientation. In the default, or first,orientation the external heat sink is below a ventilation grid and firstside 61 is below second side 62. In the inverted, or second, orientationfirst side 61 is above the second side 62. The connector ports are onthe third side. In the first orientation the third side is the left sideand in the second orientation the third side is the right side. Theterms “right” and “left” correspond to the sides of a viewer facingdisplay module 24. Accordingly, in FIGS. 3a and 3b the top side is theside opposite the support structure onto which monitor 20 rests becausemonitor 20 is in the first orientation with connector ports 32, 34, and36 on the left side.

Portable medical monitor 20 includes sensors configured to determine achange in the orientation of monitor 20 (e.g. between the first andsecond orientations) and a controller configured to rotate the imagespresented with display module 24 responsive to such rotation. Thesensors and controller are described with reference to FIGS. 22 and 23.

Referring to FIG. 3b , monitor 20 has rounded edges. A rounded firstedge 66 connects first side 61 to back side 65 and a rounded second edge68 connects second side 62 to back side 65. The bar of the handle isoperable to support the monitor at an angle to a horizontal plane, asshown in FIG. 3b , ranging at least between 15-75 degrees, permittingthe monitor to rest on the rounded first edge in the first orientationand on the rounded second edge in the second orientation. Handle brakes,described with reference to FIGS. 18 and 19, maintain a position of thehandle to support monitor 20 at a plurality of angles relative to thesupport structure onto which monitor 20 lays.

In some embodiments, rounded first edge 66 has a curvature radius equalto a curvature radius of rounded second edge 68. The curvature radiusmay be greater than 2.0 centimeters, and preferrably greater than 2.5centimeters.

FIGS. 4a, 4b, 4c, 5a, 5b, and 5c depict support features of monitor 20including latching structure 82, including bracket latch receiversoperable to receive latches of a monitor support bracket described withreference to FIGS. 8a-9b . FIG. 4b illustrates the back side of monitor20 showing the arms of handle 26 in the grooves. A ventilation grid 80is positioned between the grooves and also between second side 62 andcentral plane C_(P).

Referring to FIG. 4b , a heat sink 70 extends downward from middlesection 50 toward first side 61. Heat sink 70 includes a plurality offins 72 with slots therebetween configured to extend the externalsurface area of heat sink 70 and thereby increase cooling capacity, asis know in the art. An aperture 74 of heat sink 70 is positioned on themiddle section of the monitor. Central plane C_(P) is equidistantbetween first side 61 and second side 62 and divides middle section 50such that a first side of the middle section has a height equal to H/2and a second side of the middle section has a height equal to H/2. Asshown, an edge of heat sink 70 is aligned with an edge of middle section50. Generally, the latching structure comprises latch retainers 85 a, 85b and recesses 86 a, 86 b. In one variation, the latching structure ispart of heat sink 70 and is therefore secured to housing 22 when heatsink 70 is secured to housing 22. In another variation, a portion oflatching structure 82, e.g. a centering portion, is formed with the backwall of housing 22. Aperture 74 surrounds the portion of the latchingstructure 82 formed with the back wall of housing 22. In a furtherembodiment, the portion of the latching structure 82 is formed in aseparate device that fits between the back wall of housing 22 and heatsink 70, as described with reference to FIG. 6.

FIG. 5b is a cross-sectional view of monitor 20 at central plane C_(P)showing latching structure 82. The handle axles comprise rotation axeslying in the center plane. FIG. 5c is an expanded view of thecross-sectional view of latching structure 82. As shown, heat sink 70 ispositioned within a recess 83 formed in the back side of the monitor bylateral walls 81 c extending from a wall 81 a (which forms back side 65of housing 22) and a recessed heat sink wall 81 b connecting lateralwalls 81 c. Heat sink recess 83 is sized to receive heat sink 70therein. Heat sink 70 includes two vertical, parallel, support walls 75a, 75 b. Support walls 75 a, 75 b include a securement portion 84 a, 84b, and extending from the securement portions toward the center of theheat sink, a first latch retainer 85 a and a second latch retainer 85 b.A plurality of screws 76 pass through the securement portions to secureheat sink 70 to housing 22. Between first and second latch retainers 85a, 85 b and recessed heat sink wall 81 b of housing 22, are a firstrecess 86 a and a second recess 86 b. The latch retainers 85 a, 85 bcause latches of the support bracket to retreat until the latches enterthe recesses, at which time the latches are retained by the latchretainers. As shown, latching structure 82 includes a centeringstructure 87 comprising two vertical walls defining a cavity 88. Cavity88 is sized to receive a centering protrusion 168 (shown in FIGS. 8a and8b ) from the monitor support bracket, which facilitates latching of themonitor onto the monitor support bracket.

FIG. 6 is a perspective exploded back view of monitor 20 illustrating avariation of the latching structure described above and FIG. 7 is aperspective view of housing 22 supported by a monitor support bracket100, depicted in FIGS. 8a and 8b . Referring to FIG. 6, housing 22includes video output housing recess 400 and a heat sink recess 90defined by a plurality of walls including lateral walls 81 c extendingfrom a back wall 81 a of housing 22 toward the internal space of monitor20, and a recessed heat sink wall 81 b connecting lateral walls 81 c.Recessed heat sink wall 81 b includes a through-hole 91 through whichheat sink 70 is thermally connected to a heat generator located in theinternal space. A latching structure centering portion 92 is shownextending from recessed heat sink wall 81 b. A heat generator can be anypackaged integrated circuit that generates heat. In particular, a heatgenerator may be a packaged integrated circuit which may suffer areduced life or performance unless heat is removed from it. Examples ofheat generators include processors including central processing units,graphical processing units, FPGAs, other packaged circuits capable ofexecuting processing instructions, and the like.

The handle axles comprise rotation axes lying in the center plane. Inuse, latches 166, 170 from the monitor support bracket (shown in FIGS.8a and 8b ) pass through aperture 74. The latches are movable between afirst position and a second position and are biased to the firstposition. The latches include angled surfaces that contact first andsecond latch retainers 85 a, 85 b. During insertion the monitor ispressed toward the monitor support bracket and the latches pass throughthe aperture. The first latch retainer and the second latch retainercause the two latches to temporarily move to the second position andafter insertion the latches return to the first position with portionsof the latches positioned in the bracket latch receivers intermediatethe first latch retainer and the display module and intermediate thesecond latch retainer an the display module to secure the monitor to themonitor support bracket. The latches move away from each other and intofirst and second recesses 86 a, 86 b by operation of a biasing force.

Advantageously, heat sink 70 is manufactured from a material that isstronger than the material from which housing 22 is made, therefore heatsink 70 supports or provides support for hanging monitor 20 from themonitor support bracket. For example, heat sink 70 can be made fromaluminum or other heat conductive metals, and housing 22 can be madefrom polymers. Additionally, placing latching structure 82 in the middlesection of the monitor allows hanging the monitor in the firstorientation or the second orientation with the first or second sidessupported by the cradle of the support frame.

FIGS. 8a, 8b, 9a, 9b , 10, and 11 are views of an embodiment of asupport bracket 100 for monitor 20 including an articulating arm 101 anda longitudinal frame 130. FIG. 9b shows monitor 20 mounted on supportbracket 100. FIGS. 10 and 11 show details of longitudinal frame 130.Articulating arm 101 includes a clamp 102 hinged to a horizontallyarticulating link 104 which is hinged to a vertically articulating link106. A knob 108 can be rotated to tighten a hinge between horizontallyarticulating link 104 and vertically articulating link 106 in a knownmanner. Clamp 102 also includes a threaded rod connected to a knob 109which can be rotated to tightly secure clamp 102 to a support rodpassing through an aperture of the clamp, in a known manner. The supportrod can be an IV stand, for example.

A cable holster 110 is removably attached to clamp 102 and comprises asupport wall 111 attached to the clamp, side walls 112 a, 112 bextending from the support wall, a bottom wall 113, and an exterior wall114 opposite the support wall and connected to the lateral walls and thebottom wall, the support wall, the side walls, the bottom wall, and theexterior wall defining a volume 118 in which a power cable of themonitor may be held. Exterior wall 114 has a slot 115 along a lengththereof sized and configured to pass therethrough a portion of the powercable. A cable clip 120 and clip retainer 122 are also shown.

Longitudinal frame 130 includes a first end 131 a having a first opening132 a, a second end 131 b having a second opening 132 b, a monitorfacing side 160 between the first opening and the second opening, and atleast one aperture 135 disposed in the monitor facing side. A firstactuator 134 a at the first end of the longitudinal frame translatesthrough the first opening and a second actuator 134 b at the second endof the longitudinal frame translates through the second opening.Referring to FIG. 10, first and second actuators 134 a, 134 b includeinternal portions 134 c, 134 d which extend to contact a pair oflongitudinally aligned latches 166, 170 movable between a first positionand a second position and biased to the first position. The biasingforce may be provided by springs 134 g (shown in FIG. 11), for example,connecting internal portions 134 e, 134 f of the latches to the walls ofthe elongate member and compressible by operation of first and secondactuators 134 a, 134 b to overcome the biasing force. A gap between thepair of latches is greater in the first position than the secondposition. Each of the pair of latches includes an internal portion 134e, 134 f disposed within the longitudinal frame, a protruding portion171 b (shown in FIG. 8b ) connected to the internal portion andextending through the at least one aperture, and a latching portion 172b connected to the protruding portion distally of the monitor facingside and including an angled surface 173 a, 173 b. The angled surfacesof the pair of latches are operable to move the pair of latches from thefirst position to the second position. The first actuator and the secondactuator are also operable to move the pair of latches from the firstposition to the second position. The biasing member, for example aspring, moves the pair of latches from the second position to the firstposition.

In one variation, internal portions 134 e, 134 f of the latches areattached to internal portions 134 c, 134 d of the actuators. In anothervariation, internal portions 134 c, 134 d press against but are notattached to internal portions 134 e, 134 f. Internal portions 134 e 134f may be inserted through the opening on the monitor facing side oflongitudinal frame 130. Internal portions 134 c, 134 d may be insertedthrough first and second openings 132 a, 132 b or through the opening onthe monitor facing side of longitudinal frame 130. In some embodiments,internal portions 134 c, 134 d are inserted through the opening on themonitor facing side of longitudinal frame 130 and include one or morecircumferential ridges provided to retain internal portions 134 c, 134 dby abutting with an internal surface of longitudinal frame 130. Thecircumferential ridges do not permit insertion of internal portions 134c, 134 d throught first and second openings 132 a, 132 b in the firstand second ends 131 a, 131 b.

Returning to FIGS. 8a-b and 9, a monitor cradle 180 is sized andconfigured to receive monitor 20. Monitor cradle 180 includes a hanger182 connected to the longitudinal frame and extending downwardlytherefrom, a bottom wall 190 connected to the hanger and extendingforwardly therefrom, and a front wall 194 extending upwardly from thebottom wall. The bottom wall has a bottom surface 192 configured to theshapes of the first and second sides of the monitor. A curved surface193 is contiguous with bottom surface 192 and curved to match thecurvature of the rounded first edge and the rounded second edge so thatthe monitor can be positioned in the cradle in the first orientation orthe second orientation.

As described above, heat sink 70 of monitor 20 includes centeringstructure 87 comprising two vertical walls defining cavity 88. Cavity 88is sized to receive centering protrusion 168 extending from monitorfacing side 160. Centering protrusion 168 extends between latches 166and 170 to facilitate latching of the monitor onto the monitor supportbracket.

As shown, hanger 182 is affixed to monitor facing side 160 oflongitudinal frame 130. On the opposite side of monitor facing side 160longitudinal frame 130 is affixed to articulating link 106.

In a variation of the present embodiment, longitudinal frame 130 isformed together with hanger 182. For example, hanger 182 may be moldedwith monitor facing side 160.

FIGS. 12a and 12b illustrate monitor 20 positioned in the first, ordefault, orientation (FIG. 12a ) and in the second, or inverted,orientation (FIG. 12b ), in both cases with connector ports 32, 34, 36extending from third side 63. A graphical image 200 corresponding to anoptical image captured by the image sensor of a videoscope is presentedwith display module 24. The orientation of the monitor does not changethe orientation of the graphical image because the monitor senses thechange in orientation and rotates the graphical image in a correspondingmanner. Of course, in an alternative embodiment, connector ports 32, 34,36 can be positioned to extend from fourth side 64.

Cable connectors 202 and 204 are shown inserted into, respectively,connector ports 32 and 34. Cable connector 202 is attached to a cable ofa videoscope and cable connector 204 is attached to a cable of anothervideoscope, as described further with reference to FIG. 23. In someembodiments, each cable connector and matching connector port has avisual technology indicator to ensure the technology of the videoscopeis compatible with the technology of the respective connector port.

In some embodiments, alignment indicators 210, 211, visual and tactile,are also provided to facilitate connection of the cable connector withthe connector port. The connector port may include communication linesand power conductors to provide power to energize the image sensor ofthe respective videoscope. The visual technology indicators andalignment indicators are described in additional detail with referenceto FIGS. 15 to 17.

In some embodiments, each cable connector and matching connector porthas a visual technology indicator and alignment indicators.

Cable connectors may comprise standard cable connectors or may includetechnology and/or alignment indicators as shown in FIGS. 13a, 13b, and13c , which illustrate features of cable connector 204. The features arethe same in cable connector 202. Cable connector 204 includes aconnection section 220, a middle section 230, and a grip section 240.Middle section 230 is positioned between connection section 220 and gripsection 240. Cable 12 extends from grip

Connection section 220 includes opposing tabs 222 provided to mate withcorresponding recesses and retain cable connector 204 in place onceinserted into a connector port. Middle section 230 comprises a visualalignment indicator 210, illustratively a triangle, and a visualtechnology indicator 230, illustratively a color-coded ring. Visualalignment indicator 210 and visual technology indicator 230 may have thesame color. The cross-section of middle section 230 is substantiallycircular. Grip section 240 comprises tactile orientation indicators 242and 244. Tactile alignment indicator 242, illustratively a flat surface,enables a user to place its thumb on the surface, and thereby feel theorientation of the cable connector and be able to align it with themonitor's connector ports. Tactile orientation indicator 244,illustratively a textured surface, also allows the user to feel thetexture to determine, without looking, how to hold cable connector 202in the proper orientation relative to the monitor to thereby align thecable connector with the connector ports. As shown, the textured surfacecomprises a plurality of parallel grooves.

Up to this point several features of monitor 20 were described,including support features pertaining to the orientation of the monitor,and features pertaining to cable connectors and connector ports. Severalcomponents of monitor 20 can be characterized as being part of a videoprocessing apparatus 520, described in additional detail with referenceto FIGS. 22-24, which may but does not require the same support featuresbecause it does not include a display module. Therefore, videoprocessing apparatus 520 includes the components of monitor 20 relatedto communication and manipulation of image data but not necessarily ahandle or latching structure, although the handle and/or latchingstructure may be provided for convenience of the user. Accordingly,monitor 20 is a particular embodiment of video processing apparatus 520.

Referring to FIGS. 14a and 14b , components of monitor 20 are depictedwhich may also be comprised by video processing apparatus 520. Thesecomponents may include a circuit board 250 and, mounted on circuit board250, an internal heat sink 252 thermally coupled to a first heatgenerator circuit 254, a battery 251, a second heat generator circuit255, and a heat transfer bridge 256 thermally coupling internal heatsink 252 with external heat sink 70. Heat transfer bridge 256 maycomprise a sheet of copper physically attached to internal heat sink 252with external heat sink 70. As shown, heat transfer bridge 256 comprisesa first portion positioned between internal heat sink 252 and the firstheat generator circuit 254, which may be a memory (see memory 512 inFIG. 22), and a second portion positioned between external heat sink 70and the second heat generator circuit, which may be an FPGA (see FPGA514 in FIG. 22). In another example, the first portion of heat transferbridge 256 is sized and shaped to match, and is attached to, the finnedsurface of internal heat sink 252 instead of being positioned betweeninternal heat sink 252 and the first heat generator circuit 254. A fan253 circulates air through the fins of heat sink 252. Hot air may exitthe internal space via ventilation grid 80. The heat generator circuitsmay comprise the FPGA, a processor or central processing unit, a videographics integrated circuit, and any other circuit integrated in asingle semiconductor package and capable to processing a large number ofinstructions and thus generate heat. A heat generator circuit may alsocomprise a power regulator and/or power converter, including a DC-DCconverter. A surface 258 of heat sink 70 contacts heat transfer bridge256 which in turn contacts second heat generator circuit 255. Thermallyconductive paste or a layer of thermally conductive material may beplaced between the heat generators and the heat sinks to improve thermaltransfer, as is well known in the art. A plate 257 is placed on theinside of the back wall of the housing. Plate 257 has a through-hole,matching the location of through-hole 91, through which surface 258 isaccessible. Plate 257 also provides support to mount heat sink 70 sincefasteners 76 pass through heat sink recess wall 81 b and are securedwithin the internal space of the housing through plate 257.

In a variation of the present embodiment, fan 253 is omitted and theinternal space is passively cooled by transferring some of the heatproduced by the first heat generator circuit through the heat transferbridge to the external heat sink, where the heat is dissipated. Aportion of the heat is also ventilated through the ventilation grid.

In another variation of the present embodiment, fan 253 is provided andthe heat transfer bridge is omitted.

In another variation of the present embodiment, only an external heatsink is provided.

Monitor 20 and video processing apparatus 520 comprise one or moreconnector port. The connector port may include a flexible plug hood, asdescribed below. The flexible plug hood extends from a side of thehousing of monitor 20 or video processing apparatus 520. The flexibleplug hood may, but does not have to, include an alignment indicatorand/or a technology indicator.

Referring to FIGS. 15-17, each connector port 32, 34, 36 includes aconnector 263, 265 mounted on a medical device interface 262, 264.Connectors 263 and 265 are shown mounted on, respectively, medicaldevice interfaces 262 and 264, and more specifically on a circuit boardof each medical device interface. The medical device interfaces areremovable. Each connector port 32, 34, 36 also includes a connector ring282, 284 which, in the present embodiment, is associated with thetechnology of the respective medical device interface. The technologyfor receiving and outputting image data and for outputting power for theimage sensor, lighting device, and other components of a respectivevideoscope can vary based on the purpose or procedure for which thevideoscope is designed, the image sensor model, etc. The videoscopes maybe single-use videoscopes, in which case the monitor may be the mostexpensive component of the video system. Providing removable medicaldevice interfaces and providing technology indicators in the connectorport and videoscope cable connectors enables use of different videoscopetechnologies with the same monitor and updating of the medical deviceinterfaces to match additional or newer versions of videoscopes as theybecome available, therefore allowing an owner of the monitor to extendits effectiveness and useful life and to increase its value.

Referring to FIGS. 16a-16c and 17, connector ring 282 comprises a plughood 282 a, an intermediate portion 282 b, and a retention portion 282 dincluding an alignment cavity 282 d. The connector ring mounted on anopening in a wall of the housing. The retention portion and the plughood are larger in cross-section than the opening in the wall of thehousing in at least one radial extent, and the intermediate portion issmaller in cross-section than the opening in the wall of the housing inthe at least one extent, therefore the flexible material of theconnector ring can be bent to pass the connector ring through theopening until the intermediate portion traverses the opening, at whichtime the plug hood and the retention portion secure the connector ringin the opening. In another example the retention portion may be threadedto secure the connector ring to a threaded opening in the housing, whilestill including a flexible plug hood.

As shown, alignment cavity 282 d is a notch that fits over a protrusioninside the housing. The protrusion and alignment cavity cause connectorring 282 to fit within an aperture on the side of the monitor with thealignment indicator 287 in the correct radial orientation. Plug hood 282a includes alignment indicator 287, which may be, as shown, a notchshaped as the letter V. At least plug hood 282 a is made from a flexiblematerial. In the present embodiment, the connector ring is made from theflexible material, for example silicone or an elastomeric polymer. Theconnector ring may be molded or machined. Flexibility facilitatesinsertion of the cable connector, or plug, through the plug hood intothe connector of the medical device interface. Additionally, flexibilityprevents damage to the plug hood in case the monitor or VMM isaccidentally dropped or hit. Thus, because the plug hood will not bedamaged by contact, it can extend further than prior art plug hoods.Additionally, flexibility facilitates “blind” (by feel, without looking)insertion of a cable connector through plug hood 282 a for coupling witha connector 263, 265. Altogether, the tactile and visual alignmentindicators facilitate visual and blind connections, as desired, whichcan be made more quickly than without the indicators.

The notch of alignment indicator 287 may be surrounded by a frame 288 ofmaterial of a color different than the color of the remainder of theconnector ring to highlight the position of the notch. For example,frame 288 may be white while connector ring 282 may be blue, green, oranother color.

Turning attention now to the handle of monitor 20, as described withreference to FIGS. 2a-5c , the handle can be maintained in one of manypositions by a handle position brake. Referring now to FIGS. 18 and 19,the monitor includes a handle position brake on each side. FIG. 18illustrates an embodiment of a handle position brake 300 viewed frominside housing 22 and therefore showing the internal surface of the wallportion forming groove 42, denoted by numeral 330 in FIG. 18. Handleposition brake 300 includes a threaded nut 302 secured to handle axle51, a first disk 304, a second disk 306, and a spring 308 betweenthreaded nut 302 and first disk 304, spring 308 causing a surface of thefirst disk to press against a surface of the second disk to create abraking force to maintain handle 26 in one of the plurality of positionsas described above. An additional disk 310 is shown between spring 308and threaded nut 302. The surface of the first disk can be grooved andthe surface of the second disk can also be grooved to increase thebraking force relative to ungrooved, or flat, disk surfaces. Groovesprovide one form of texturing. Other textures may be applied to increasefriction between the disk's surfaces. The grooves can be distributedevenly radially, for example every 10-20 degrees, so that protrusionsbetween each pair of grooves can fit in grooves of the opposing disk toprovide a discrete position. Thus, for example, if the grooves arespaced 15 degrees apart, the brakes will have different handle positionsat 15 degree intervals.

Second disk 306 comprises two keys protruding parallel to handle axle51. One key penetrates an aperture of a right-hand rotation stop 320 andthe other penetrates an aperture of a left-hand rotation stop 322. Eachrotation stop comprises a circular portion through which handle axle 51passes and extending from the circular portion a first arm perpendicularto handle axle 51 and a second arm extending therefrom in parallel tohandle axle 51. The rotation stops prevent rotation of second disk 306.

A reinforcement block 332 is affixed to housing 22 on the opposite sideof which handle position brake 300 is mounted. A portion ofreinforcement block 332 extends over wall 330 and between wall 330 andleft-hand rotation stop 322 to reinforce wall 330.

FIG. 19 depicts an external view of a portion of monitor 22 overlappinghandle position brake 300. A distal end of handle axle 51 oppositethreaded nut 302 has a through-hole. The first end of arm 46 fits in thethrough-hole and is secured therein by a screw 334. Thus, pivotingmovement of arm 46 causes handle axle 51 to pivot only when the frictionbetween the surfaces of the first and second disks 304 and 306 isovercome by the force applied to arm 46. Otherwise, the friction holdsarm 46 in its position. A distal end of the handle axle may be supportedby a bushing 311.

In some variations of the present embodiment, monitor 20 does notinclude a handle or a handle position brake.

In some variations of the present embodiment, monitor 20 includes ahandle and a handle position brake, and the handle is not pivotallycoupled to the housing of the monitor at a middle section thereof.

Turning attention now to the video output by monitor 20 or videoprocessing apparatus 520, a video output housing recess facilitatesconnection of video cables while retaining the connectors of the videocable substantially within the recess to enhance retention and preventaccidental disconnection thereof. Referring to FIGS. 20a, 20b, and 20c ,video output housing recess 400 is formed by lateral walls 401, 402, 404and 405, and a bottom wall 403 having an external surface 403 a and aninternal surface 403 b. Connectors 420 a, 420 b, and 420 c areaccessible through wall 402. Bottom wall 403 is disposed at an anglebeta which is at least 4 degrees relative to the surface of the displayscreen. Preferrably, beta is at least and including 5-25 degrees, andeven more preferrably beta is at least and including 6-25 degrees.Connector 420 a, for example an HDMI connector, is also aligned at anglebeta. Connector 420 a is mounted on a video ouput board 410. Optionally,video output board 410 is also supported inside housing 22 at anglebeta. A video plug 421 is shown in FIG. 20c plugged into outputconnector 420 a. Advantageously, aligning the connector and the bottomwall of the video output housing recess enables a user to more easilyconnect the plugs with the connectors of the video output board.Optionally, wall 404 is curved to further facilitate manipulation ofplugs with the connectors of the video output board. Wall 404 isopposite 402. The connectors can, but do not have to be, video outputconnectors. Connectors can be for ethernet, coaxial, and other types ofcables and the cables can provide bi-directional communications and/orpower.

Another feature of monitor 20 or video processing apparatus 520 is apower receptacle assembly. Referring to FIG. 21, a power receptacleassembly 500 comprises a power socket 501 mounted on circuit board 250and a corresponding hole 502 in the back wall of housing 22. A powercord plug passes through hole 502 to enter power socket 501 and throughpower socket 501 provides power to the circuits on circuit board 250 andthe medical device interfaces. Advantageously, this design requires orcauses removal of the power cord plug before the back portion of housing22 is removed from the front portion to, for example, swap, remove, oradd, medical device interfaces, which ensures the circuits are powereddown before the back portion of housing 22 is removed to provide accessto the medical device interfaces. Additionally, aligning hole 502 withpower socket 501 mounted on the circuit board, which can be referred toas a motherboard, eliminates additional cables in the internal spacethat would be required if, for example, power socket 501 were mounted ona side of the housing.

As described above, monitor 20 is advantageously operable in default andinverted orientations and can be connected to one or more medicaldevices, which may, but do not have to, be videoscopes. Thus, monitor 20includes video processing circuits operable to receive image data,present a graphical user interface to allow a user to manipulate imagedata with a touch screen, and, optionally, output a video signal toallow remote viewing of the images presented with the touch screen.

Variations of monitor 20 can be provided with various features ofmonitor 20 but including other features. For example, it might not bedesirable to provide a touch screen, or it might be desirable to omit adisplay module altogether. Omission of the display module might bebeneficial to take advantage of evolving video display technologieswhich improve resolution and reduce cost. Provision of exchangeablemedical device interfaces allows for adoption of evolving image sensorand videoscope technologies, thus use of existing or future-developedexternal video displays could allow presentation of higher resolution orotherwise improved video. Use of external video displays could alsoleverage existing capital investments. Use of wall-mounted videodisplays could also reduce reliance on IV poles and, generally, clutter.

Video processing circuits and other components will now be describedwith reference to FIGS. 22-24. FIG. 22 depicts example components ofmonitor 20. Several components are part of a VMM 21. It should beunderstood that VMM 21 can, but does not have to be, a physical moduleindependent of other components. Instead, VMM 21 is described in termsof its function to simplify description, and the components that performthe functions can be arranged in any convenient manner. Accordingly,monitor 20 includes VMM 21, display module 24, and, optionally, anorientation sensor 518. The functionality of orientation sensors wasdescribed above. VMM 21, display module 24, and an orientation sensor518 are supported by housing 22, as described above. As shown, VMM 21includes medical device interfaces 262, 264, and 266. VMM 21 couldinclude fewer medical interfaces and might include a medical deviceinterface that is not removably coupled.

VMM 21 also includes a processor 510, memory 512 including graphicaluser interface (GUI) logic 513, a field-programmable gate array (FPGA)514, video output board 410, a user interface 516, and a microphone 517.User interface 516 may comprise a wireless interface operable to receiveuser inputs via a mouse, keyboard, or other physical user input devices.Example wireless interfaces include Bluetooth and Zigbee controllers.User interface 516 may also comprise a USB port to receive a USBconnector including the wireless interface or a USB connector of a wireduser input device. Thus, VMM 21 provides for flexibility in receivinguser inputs via various user input devices, regardless whether a displaymodule is integrated therewith.

FPGA 514 is optionally provided because it is capable of rapid power-up(i.e. short boot-up time) and thus is useful in emergency situations.FPGAs may also be provided in the medical device interfaces for the samereasons. FPGAs process data very fast compared to othermemory/instruction combinations and are re-programmable. Therefore FPGAsfacilitate presentation of a live view of the images captured by thevideoscope in real-time with minimal latency so that the physicianobserving the live view can take immediate actions even in emergencysituations. As technology evolves, the functionality of FPGA 514 may becombined with processor 510. VMM 21 is therefore not limited to theprecise packaged integrated circuits described with reference to FIG. 22but can be constructed to take advantage of design and cost targets andfuture video processing technologies. For example, faster/more costlymemory may be used to increase graphics processing speed. Graphicsprocessing may be provided in the FPGA or a processor that incorporatesgraphics processing logic may be used instead.

FIG. 23 illustrates a system including monitor 20 and three videoscopes1 a, 1 b, 1 c communicatively coupled to monitor 20 via cables 12 a, 12b, and 12 c. The videoscopes may comprise, for example, an endotrachealtube with an image sensor at the distal end thereof, a videolaryngoscope, an endoscope, a duodenoscope, a colonoscope, an ENT scope,and any other medical device adapted for insertion into a living bodyand having an image sensor to capture views of body tissues. An externaldisplay device 524 is communicatively coupled to monitor 20, for examplevia video output board 410 and an HDMI cable.

Theconnector port(s) may include a flexible plug hood, as described above.The flexible plug hood may extends from a side of housing 522. Any ofthe above-described connector port configurations may be used, includingthose comprising various indicators technology and orientationindicators.

In some embodiments, PVA 520 is devoid of a display module.

In some embodiments, PVA 520 is devoid of a handle pivotally attached tothe back wall of the housing and of grooves sized and shaped to receivethe arms of the handle.

The term “logic” as used in this patent application includes softwareand/or firmware executing on one or more programmable processingdevices, application-specific integrated circuits, field-programmablegate arrays, digital signal processors, hardwired logic, or combinationsthereof. Therefore, in accordance with the embodiments, various logicmay be implemented in any appropriate fashion and would remain inaccordance with the embodiments herein disclosed. Logic may compriseprocessing instructions embedded in non-transitory machine-readablemedia (e.g. memory).

GUI logic 513 comprises processing instructions to generate a GUIpresented with display module 24 and/or external display device 524. TheGUI can be responsive to user inputs received via the touch screen orother user inputs. GUI logic 513 may process an output signal fromorientation sensor 518 indicative of an orientation of monitor 20, andto present the GUI in an orientation based on the signal fromorientation sensor 518.

Processor 510 receives image data from medical device interfaces 262,264, and 266 and outputs video signals incorporating the GUI and imagedata. Image data may be referred to “live images” or “live video” ifthey are received substantially in real-time from the videoscopes. Thevideo signals may be received by a memory buffer and the buffer may beread by the display module or video output card to present the GUI andimages. Techniques for presenting images are well known, includingtechniques using buffers or mapped memory.

GUI logic 513 may present the GUI depending on the orientation signalfrom the orientation sensor or a user instruction to invert the view. Aview corresponds to the display area of a display screen. The GUI maycomprise first and second panels provided side-by-side in the view. Thesecond panel presents live images and is positioned on the right side ofthe view, with the first panel positioned on the left side of the view.Even when the monitor orientation changes, the first panel remains onthe left of the second panel.

The GUI may present in the first panel a small version of live imagesprovided by a second videoscope and the user may use the GUI to switchthe live images from the first and second videoscopes so that the imagesfrom the second videoscope are presented in the second panel while theimages from the first videoscope are reduced and presented in the firstpanel. The last videoscope connected to a connector port may be shown inthe second panel by default. However the views from the differentvideoscopes can selected by the user with the GUI for presentation inthe first or second panel or not displayed at all.

The GUI may present various icons corresponding to actions selectable bythe user with any of the above-described user input devices, to forexample store a copy of a live image, store a portion of videocorresponding to live images, invert the views, apply correction curvesto the image data to reduce overexposure, etc.

Additional examples within the scope of the disclosure are listed below.
